Subfloor/thinset question
I am retiling a small, 23 Sq/ft half bathroom that was previously done very poorly with very little thin set and thin tiles that cracked.
The tiles came up very easily, but I'm having trouble getting all of the thin set off the of the plywood subfloor. I've gotten much of it off and have ground down the spots that are left to a very thin and smooth surface. Is this okay to apply the tiles to as long as I make sure there is nothing loose? I'm avoiding cement board because I don't want to raise the floor any more than the much thicker tiles I'll be installing will.
Any advice would be appreciated. Thank you.

Additionally, what's the size, spacing and unsupported span of the floor joists and what is the composition of the current subfloor?
FWIW, I would remove the layer of plywood on which the tiles were set rather than try to remove the thinset from it.

For 23 sf using Ditra or a similar membrane (I think there are several brands?) would seen a reasonable approach. You might be able to buy that small amount from a tile setter or company in bulk as opposed to buying a whole roll at retail.
